This Astro-Sonic was made in August of 1964. It sold in
February 1965. Model 2ST631 is a 20 transistor AM-FM-FM
MPX Receiver with a four speed Automatic Record Changer. The
Receiver chassis is R205-12-00. The Record Changer is a Series
W603. Underneath the platter mat is W603-20-02 and on the
bottom of the changer is Model W603-18-02 part number
52345821. Go figure. The cartridge number is an Electro-Voice
158. I'm currently using a 365-DS77 needle, both tips .0007,
one diamond and one synthetic sapphire. If you want to play 78
RPM records get a 365-DS73.
